Question about 1995 Chevrolet G20
I have replaced fan motor, it works fine now. I have replaced control switches, the whole panel. All the vac lines are on,
I would recheck to make sure that control switches are hooked up. other than that you could check to make sure your air ducts are connected.

Does your van have the serpentine belt? If so maybe I can help, I replaced the Power steering pump on my 90 G20 a couple of weeks ago. The trick is that you need to pull the pump pulley which is pressed on to access the mounting bolts which attach the pump to the engine. Harbor Freight tools sells a great tool designed for this job for $20.00. Once you have the correct tools, remove the serpentine drive belt. You may also need to remove the fan shroud. the pump shaft looks like it has an allen socket in the center, but this is for use in the manufacturing process, and will not come out. Place the puller tool on the pulley following tthe instruction that come with the tool, and remove the pulley. loosen, but do not remove the nut on the high pressure hose connection. use a pair of **** pliers to cut and remove the crimp clamp on the low pressure hose. If your pump has the remote reservour loosen the clamp on the reservour hose also. Remove the three mounting bolts, place a large pan under the pump to catch drips, and remove the prevously loosened hoses. there will be fluid leaking all over and the pump should come free, There are two types of replacement pump sold. With and without reservour. This reservour is a metal cover that fits over the back of the pump, and should not be confused with the reomte revervour found on some newer models which is next to the battery. This reservour is held in place be two throught the pump bolts which are removed at the back of the pump. If your new pump has a reservour you will probably still need to remove these bolts and put them in the replacement pump as most are shiped without these bolts. If you replacement pump comes without a reservour pull the bolts, the reservour should pull off of the old pump and slide onto the new one. check the o rings and replace the through the pump bolts. Installation is the reverse of removal execpt that 1/2" hose clamps replace the crimp clamps on the low pressure hose, and the puller tool is set up differently to replace the pulley. Finally if you don't flush contaminants out of the system your repair will last maybe a week. www.cardone.com has a great article about power steering flushing, read it before you start Good luck.

SOURCE: There is no air flow
You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!
Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!
The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!
I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!
Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!
3 on the Drivers side and 2 on the Passengers side!!
But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

The problem is a 1/8 diameter hose that runs from the front of the engine over the top and connects at the rear of engine on the drivers side. It is a vacuum hose #GM15967970 It cost about $6.22 at your GM dealer. Hope this helps Bill. My E-Mail is Uflyups@aol.com

yes the heater controls are vacum however the blower motor is not. a new control panel is an option and may fix it. if it was my blazer i would first check the fuse boxes onder the hood and in the side of the dash driver side. if they are good i would go to the nearest auto parts store and buy a test light. this will aid you in making sure what the problem is before you go spending money on replacement parts. the blower motor is in one of two places. its most likely under the dash on the passenger side. there is a cover that you will have to remove directly under the glove box. once removed you should see a large red and a large black wire. these are the power and ground for the blower motor . in some gm's these wires go into a resistor. the harness plugs into the resistor and the blower motor wires come out of it. ok now that we are a little bit familiar with our suroundings the red wire i told you about is the hot wire if you ground the clamp on the test light to the door hindge. (make sure its a good ground by touching the positive batter terminal. if the test light lights its a good ground )now unplug the blower motor and touch the metal posts in the end of the plug that belong to the red wire. if it lights when the key is on and the blower control is on in all posisions you need a blower motor. if it does not then you need a blower motor resistor.

You actually have two separate problems. The brake pull to the right is indicating the left side brake is not working properly. You will want to remove the left front wheel, collapse the caliper piston and make sure the caliper is floating freely on its mounts.
With the piston collapsed you should be able to slide the caliper inboard and outboard of the rotor. If not, you will want to remove the attachment pins, clean and lubricate the pins. If they are grooved or worn you will have to replace them.
The second issue of the ABS light is indicating the system has detected an electrical sensing or control problem. Take the vehicle to your local Auto Zone or Advance Auto and ask them to scan the vehicle for trouble codes. They will scan it for you at no charge.
Chances are you will find a wheel speed sensor problem at one of the wheels.
Write the codes down and respond back, we can start diagnosing the problem,
Good luck, let me know.
